The Numerical Sensitivity Analysis of the Oscillating Flow and Heat Transfer in Inertance Tube Pulse-Tube Cryocooler
Recently, great deals of research efforts have been made to look for the basic theory of the oscillating flow and heat transfer. Considering the complex progress of it, especially in Inertance Tube Pulse-Tube Cryocooler (ITPTC), the dominant factors have to be found to accomplish the modeling experiment and the numerical simulation, and these factors are called non-dimensionless dominant factors. As a result, mastering the sensitive inter-zones of these factors is crucial for experiments or computational fluid dynamics (CFD). Based on the experimental data and the CFD model, the numerical sensitivity analysis is applied in the oscillating flow and heat transfer with the object function of the lowest temperature and the cooling capacity. The similarity principle obtained from the numerical sensitivity analysis is in agreement with the experimental data, and further explanation is given by analyzing the deviation of Sr, Re and Ma in a model from its prototype. These results can be applied in the modeling experiment of ITPTC, and they indicate the need of further investigation of the importance of other non-dimensionless factors.
